Answer:
4. The mass of 5 pebbles = 5 x 0.05 kg = 0.25 kg
Kinetic energy = 1/2 x mass x velocity^2
Kinetic energy = 1/2 x 0.25 kg x (25 m/s)^2 = 78.125 J
Estimate: Around 80 J
5. Mass of sports car = 1200 kg
Speed of sports car = 80 mph = 35.76 m/s (approx.)
Kinetic energy = 1/2 x mass x velocity^2
Kinetic energy = 1/2 x 1200 kg x (35.76 m/s)^2 = 906720 J
Estimate: Around 900,000 J
6. Mass of rock = 22 kg
Speed of rock = 9.0 m/s
Kinetic energy = 1/2 x mass x velocity^2
Kinetic energy = 1/2 x 22 kg x (9.0 m/s)^2 = 891 J
Estimate: Around 900 J
7. C. 200J
When the mass of an object doubles, its kinetic energy also doubles.
8. D. 400 J
When the velocity of an object doubles, its kinetic energy increases by a factor of four.
9. The kinetic energy of an object is given by the formula KE = 1/2 mv^2, where m is the mass of the object and v is its velocity. Comparing the two balls, we can see that the first ball has a kinetic energy of 1/2 x 1.0 kg x (10 m/s)^2 = 50 J. The second ball has a kinetic energy of 1/2 x 10 kg x (1.0 m/s)^2 = 5 J. Therefore, the 1.0 kg ball moving at 10 m/s has more kinetic energy.
10. Kinetic energy = 1/2 x mass x velocity^2
100 J = 1/2 x 2.0 kg x velocity^2
velocity^2 = 100 J / (1.0 kg x 2.0) = 50
velocity = √50 m/s
Estimate: Around 7 m/s
11. Kinetic energy = 1/2 x mass x velocity^2
125000 J = 1/2 x 400 kg x velocity^2
velocity^2 = 125000 J / (200 kg) = 625
velocity = √625 m/s
Speed of motorcycle = 25 m/s
Estimate: Around 25 m/s
12. The kinetic energy of the horse and rider is given by KE = 1/2 mv^2, where m is the mass and v is the velocity. Since the kinetic energy should remain the same, we have KE = 1/2 m1v1^2 = 1/2 m2v2^2, where m1 is the mass of the horse and rider, m2 is the mass of the horse and a 100 kg rider, v1 is the initial speed, and v2 is the final speed we need to find.
Solving for v2:
v2 = sqrt((m1/m2)*v1^2) = sqrt((350+50)/100 * 19^2) = 25.85 m/s
Estimate: Around 25 m/s

In places of hot climate it is advised that the outer walls of houses be painted white. Explain.
Answers
Darker colors absorb heat, While lighter colors don't. If a house is painted black in Arizona, The black color will absorb the heat making the temperature inside the house very hot even with the AC on. If a house in Arizona is painted White, The heat will bounce off the White color, making the temperature inside the house cooler.
Hope this helps!
Answer:
Have you ever noticed people working outside in the hot sun and how you never really see them wearing black shirts or pants. This is because dark colors absorb heat, however light colors, such as white, do the exact opposite. Instead of absorbing the heat from the light, light colors reflect it. So people usually paint there houses lighter colors in hot places to keep their there houses from absorbing heat so it does not cost them so much on electricity bills for air conditioning.

What is potential energy ?Potential Energy that depend upon the relative position of various parts of system . It is an energy possessed by an object by virtue of its position or configuration.
mass(m) = 10kg
g (acceleration due to gravity) = 9.8m/s^2
altitude(height (h)) = 400m
Meteor's Potential energy = m * g * h
= 10 * 9.8 * 400 = 39200 J

Black to move and capture a hanging piece . Select the best move
A) Nxg3
B) Bxg3
C) Qxg5
Answers
Answer: A
Explanation:The Pawn moves directly forward, never backward or to the side. Pawns capture a piece that is one square diagonally forward. Though Pawns normally cannot move diagonally, this is the only way they capture.
Based on the information provided, the best move to capture a hanging piece would be: A) Nxg3
What would be the best move to capture a hanging piece ?Nxg3 would be the best move to capture a hanging piece.
This move involves sacrificing the knight to capture the hanging piece, which could be a bishop or pawn, depending on the position of pieces. After Nxg3, the opponent may capture the knight with different piece, but the player who made the move will have successfully captured the hanging piece.
However, it's important to note that the best move ultimately depends on the overall strategy of the player and the position of the other pieces on the board.

How does the sport curling relate to Newton’s Second Law of Motion?
Answers
Curling is a sport in which players slide stones across a distance of ice toward a target area. The purpose is to accumulate the loftiest score for a game by making monuments rest closest to the center of the target at the end of each side. There are two brigades. Each platoon is trying to keep the other platoon's monuments down from the target by knocking their monuments out of the way.
Newton's Second Law " The acceleration of an object is directly commensurable to the net force acting on it and is equally commensurable to its mass. The direction of the acceleration is in the same direction as the net force acting on an object." This relates to the formula F = ma. The mass of the determinedness monuments in curling is 38 to 44 pounds or 17.3 to 20 kg. The thing of the sweepers is to control the acceleration of the gravestone by reducing disunion on the ice, which affects the force with which the gravestone is suitable to impact the other monuments.

https://brainly.com/question/25545050
Second law-
Newtons second law occurs during curling when the delivery man, such as Glenn Howard, applies force to the stone pushing down the lane to the target while friction pulls it back the other way to a slow stop. The mass of the stone is 40lbs and the net force of everything on item will give you its slowly decreasing acceleration. Otherwise known as, F=mA.
Third law-
This law can be exerted in the sport of curling when the force behind a stone being delivered is transferred into another stone that is at rest, where the energy and force of one moving object is transferred to another. This almost completely stops the original stone, and gives some speed to the stone(s) it collides with.

Gravity is a fundamental force that acts on all objects with mass, including the Earth itself, but it does not cause changes or modifications to the Earth's surface features. Instead, gravity influences the movement of materials and the shape of the Earth's surface by exerting a pulling force on objects.
